We had AT&T for years. When we would go to Mexico, we would add an international calling plan for $5. Then we would cancel it when we got home. We have switched to Verizon, and they said there is not an international plan I can add for Mexico (although they have them for other countries). I would have to switch to a totally new plan which wouldn't make sense for us. The rate for a call is $.99/minute!! I remember years ago getting a calling card, and calling home that way. We are staying at the Valentin Imperial Maya. I am assuming there are no pay phones, and usually it still costs a fortune to call from your room. Does anyone know if there are pay phones there? Any other suggestions? Thanks!
